How do I make it?

Fill the glass with the boiling water and leave to stand in order to pre-heat the glass. Once warm, empty the glass.

Pour the boiling brewed coffee into the now-empty tall glass until it is 3/4 full.

Dissolve the brown sugar into the coffee and stir.

Using a tablespoon, slowly pour the whipped cream onto the back of the spoon in order to prevent the cream sinking into the coffee.

Your Irish Coffee should now have a floating (and hopefully even) topping to fill the remaining 1/4 of the glass. To add extra festivity, add grated nutmeg to further compliment the nutty taste Irish Coffee offers.
